Mass air flow sensor
Hello again I am having trouble with my disco II. I think my mass air flow sensor is bad and I am wondering how they go out. I recently had an oil change and they checked my air filter (which was dirty). Got a new air filter and probelms started. Check engine light came on and rover is running bad. Tranny feels hot through the floor. Brakes locked up on one wheel. Abs traction control and down hill descent lights are all on. I tried cleaning the MAFF with crc mas air flow cleaner. Still no luck. I was told a weak battery could cause problems changed battery and no luck. The OBD II codes are P1590 P0102 and P1884. Is the next best step to repalce Mass air flow. Where is the best place to buy. Recently flushed radiator and coolant. Also replaced spark plugs. Land rover has 144,000 miles on it.

Im having the same problem, I changed the air filter and no change, my codes are P1171, P1174 and generic code P0174, all are indication of lean mixture, I sure don't want to replace an O2 sensor knowing something else could be the problem, my problem started a few days after I replace the two front tires on my 2001 Disco II 110000 miles...

P1590 is a rough road code, you need either the hub is going bad, or one of your brake components is failing.
P0102/P1884 are MAF related. No real difference in where you buy the replacement.

The 1590 is your 3 amigos and the 1884 will go away when you replace the MAF.
